Development of a HACS User Interface Module.
Abstract
The Hazard Assessment Computer System (HACS) is one of six major components of the U.S. Coast Guard's Chemical Hazards Response Information System (CHRIS). HACS is a computerized system consisting of chemical spill models and containing all necessary physical and chemical property data to permit hazard assessments to be performed for 900 commonly shipped chemicals. The User Interface Module (UIM) provides for fully interactive operation of HACS with remote access for users to the central computer facility by means of remote terminals. The final report provides documentation of the internal structure of the HACS/UIM as developed for use by the USCG on the Cybernet System of Control Data Corporation. the UIM controls the user interaction with HACS by means of a question and answer dialog; all user responses are interpreted by the UIM without input formatting restrictions using a series of terminal input utility functions. An overview of the internal structure of HACS/UIM is given in terms of both sub-program modules and sequence of operations. Descriptions of all required HACS data files are given; these include a chemical and physical property data file for the 900 hazardous chemicals. Additional descriptive text and detailed input data explanations are stored in external files for retrieval and display under user control. Complete program listings for the HACS/UIM and associated computer programs are included in the report. (Author)
